26 4. AMI BIOS Setup 4.1 Introduction This manual discusses AMI Setup program built into the ROM BIOS. The Setup program allows users to modify the basic system configuration. This special information is then stored in batterybacked CMOS RAM so that it retains the Setup information when the power is turned off. 4.2 Starting Setup The AMI BIOS is immediately activated when you first power on the computer. The BIOS reads the system information contained in the CMOS and begins the process of checking out the system and configuring it. When it finishes, the BIOS will seek an operating system on one of the disks and then launch and turn control over to the operating system. While the BIOS is in control, the Setup program can be activated in one of two ways: 1. By pressing <Del> immediately after switching the system on, or 2. by pressing the <Del>key when the following message appears briefly at the bottom of the screen during the POST. Press DEL to enter SETUP. If the message disappears before you respond and you still wish to enter Setup, restart the system to try again by turning it OFF then ON or pressing the "RESET" button on the system case. You may also restart by simultaneously pressing <Ctrl>, <Alt>, and <Delete> keys. If you do not press the keys at the correct time and the system does not boot, 25

27 an error message will be displayed and you will again be asked to... PRESS F2 TO CONTINUE, DEL TO ENTER SETUP 4.3 Using Setup In general, you use the arrow keys to highlight items, press <Enter> to select, use the PageUp and PageDown keys to change entries, press <F1> for help and press <Esc> to quit. The following table provides more detail about how to navigate in the Setup program using the keyboard. Up arrow Move to previous item Down Move to next item arrow Left arrow Move to the item in the left hand Right arrow Move to the item in the right hand Esc key Main Menu -- Quit and not save changes into CMOS Status Page Setup Menu and Option Page Setup Menu -- Exit current page and return to Main Menu PgUp key Increase the numeric value or make changes PgDn key Decrease the numeric value or make changes + key Increase the numeric value or make changes - key Decrease the numeric value or make changes F1 key General help, only for Status Page Setup Menu and Option Page Setup Menu F2 /F3 key Change color from total 16 colors. F2 to select color forward, (Shift) F2 to select color backward F4 key Reserved F5 key Reserved F6 key Reserved F7 key Reserved F8 key Reserved F9 key Reserved F10 key Save all the CMOS changes, only for Main Menu 26

28 4.4 Getting Help Press F1 to pop up a small help window that describes the appropriate keys to use and the possible selections for the highlighted item. To exit the Help Window press <Esc> or the F1 key again. If, after making and saving system changes with Setup, you discover that your computer no longer is able to boot, the AMI BIOS supports an override to the CMOS settings which resets your system to its defaults. The best advice is to only alter settings which you thoroughly understand. To this end, we strongly recommend that you avoid making any changes to the chipset defaults. These defaults have been carefully chosen by both AMI and your systems manufacturer to provide the absolute maximum performance and reliability. Even a seemingly small change to the chipset setup has the potential for causing you to use the override. 4.5 Main Menu Once you enter the AMIBIOS CMOS Setup Utility, the Main Menu will appear on the screen. The Main Menu allows you to select from several setup functions and two exit choices. Use the arrow keys to select among the items and press <Enter> to accept and enter the sub-menu. 27

29 Note that a brief description of each highlighted selection appears at the bottom of the screen. The main menu includes the following main setup categories. Some systems may not include all entries. Field Standard CMOS Setup Advanced CMOS Setup Advanced Chipset Setup Power Management Setup Description Use this menu for basic system configuration. Use this menu to set the Advanced Features available on your system. Use this menu to change the values in the chipset registers and optimize your system's performance. When Disabled, SMI will not be initialized, and complete power management functionality is removed until this option is set to 28

30 Enabled. PCI / Plug and Play Setup Peripheral Setup Hardware Monitor Setup Auto-detect Hard Disks Change Supervisor Password Auto Configuration with Optimal Settings Auto Configuration with Fail-Safe Settings Save Settings and Exit Exit Without Saving This entry appears if your system supports PnP / PCI. Use this menu to specify your settings for integrated peripherals. Use this menu to monitor your hardware. Use this menu to specify your settings for hard disks control. Use this menu to set User and Supervisor Passwords. Use this menu to load the BIOS default values that are factory settings for optimal performance system operations. While AMI has designed the custom BIOS to maximize performance, the factory has the right to change these defaults to meet their needs. Use this menu to load the BIOS default values for the minimal/stable performance for your system to operate. Save CMOS value changes to CMOS and exit setup. Abandon all CMOS value changes and exit setup. 29

31 4.6 Standard CMOS Setup The items in Standard CMOS Setup Menu are divided into 10 categories. Each category includes no, one or more than one setup items. Use the arrow keys to highlight the item and then use the <PgUp> or <PgDn> keys to select the value you want in each item.

The option determine if AMIBIOS should remove an IRQ from the pool of available IRQs passed to devices that are configurable by the system BIOS. The available IRQ pool is determined by reading the ESCD NVRAM. If more IRQs must be removed from the pool, the end user can use the option to reserve the IRQ by assigning an ISA/EISA setting 41

43 to it. Onboard I/O is configured by AMIBIOS. All IRQs used by onboard I/O are configured as PCI/PnP Peripheral Setup The Peripheral Setup allows you to configure you system to most effectively save energy while operating in a manner consistent with your own style of computer use. OnBoard Serial Port 1/Port 2/Port 3/Port4 This option specifies the base I/O port address of serial port 1. The settings are Auto (AMIBIOS automatically determines the correct base I/O port address), Disabled, 3F8h, 2F8h, 2E8h, or 3E8h. OnBoard Parallel Port This option specifies the base I/O port address of parallel port on the motherboard. The settings are Disabled, 378h, 278h, or 3BCh. 42

44 Parallel Port Mode This option specifies the parallel port mode. The settings are Normal, Bi-Dir, EPP, ECP. Normal: The normal parallel port mode is used. Bi- Dir :Use this setting to support bi-directional transfers on the parallel port. EPP: The parallel port can be used with devices that adhere to the Enhanced Parallel Port(EPP) specification. EPP uses the existing parallel port signals to provide asymmetric bi-directional data transfer driven by the host device. ECP: The parallel port can be used with devices that adhere to the Entended Capabilities Port(ECP) specification. ECP uses the DMA protocol to achieve data transfer rates up to 2.5 Megabits per second. ECP providessymmetric bi-directional communication. EPP Version EPP data or address read cycle 1.9 or 1.7 Parallel Port IRQ This option specifies the IRQ used by the parallel port. The settings are Auto, (IRQ)5, (IRQ)7. Parallel Port DMA Channel This option is only available if the setting for the Parallel Port Mode option is ECP. This option sets the DMA channel used by the parallel port. The settings are DMA Channel 0, 1, or 3. On Board AC 97 Audio Enable or Disable AC 97 Audio Function. 43

45 4.12 Hardware Monitor Setup 4.13 Change Supervisor Password You can set either supervisor or user password, or both of them. The differences between them are: Supervisor password: Users can change the options of the setup menus. User password: Users do not have the right to change the options of the setup menus. When you select this function, the following message will appear for you to create a password. ENTER PASSWORD: Type a password of up to eight characters in length and press Enter. Confirm the password by entering it again and press Enter. Previous password in CMOS memory will be cleared once a 44

46 new password is created. To abort, press Esc. When a password is enabled, you will be prompted to enter it every time you enter Setup. This prevents an unauthorized party from changing any part of the system configuration. You can also require BIOS to request a password every time your system is rebooted. This would prevent unauthorized use of your computer. You can determine when the password is required in the BIOS Features Setup Menu and its Security option. PASSWORD ENABLED/DISABLED: To disable a password, press Enter when you are prompted to enter the password. Then confirm the selection. Once the password is disabled, the system will restart and you can enter Setup freely. 45

47 Appendix A: Watchdog Timer The Watchdog Timer is a device to ensure that standalone systems can always recover from abnormal conditions that cause the system to crash. These conditions may result from an external EMI or a software bug. When the system stops working, hardware on the board will perform hardware reset (cold boot) to bring the system back to a known state. Three I/O ports control the operation of Watchdog Timer. 443 (hex) Write Set Watchdog Time period 443 (hex) Read Enable the Watchdog Timer 043/843 (hex) Read Disable the Watchdog Timer Prior to enable the Watchdog Timer, user has to set the time-out period. The resolution of the timer is 1 second and the range of the timer is from 1 sec to 255 sec. You need to send the time-out value to the I/O port 443H, and then enable it by reading data from the same I/O port 443H. This will activate the timer that will eventually time out and reset the CPU board. To ensure that this reset condition will not occur, the Watchdog Timer must be periodically refreshed by reading the same I/O port 443H. This must be done within the time-out period that is set by the software, please refer to the example program. Finally, we have to disable the Watchdog timer by reading the I/O port 843H or 043H. Otherwise the system could reset unconditionally. A tolerance of at least 5% must be maintained to avoid unknown routines in the operating system (DOS), such as disk I/O that can be very time-consuming. For example, if the time-out period has been set to 10 seconds, the I/O port 443H must be read within 7 seconds. 46

51 Appendix C: How to use Wake-Up Function FIR-C650 provides two kinds of Wake-up function. This page describes how to use Modem Wake-Up and LAN Wake- Up functions. Wake-Up function only works with ATX power supply. Wake-Up On Modem(Ring): You must set the option Wake-Up On LAN/Ring of CMOS SETUP to be enabled. ATX power supply will be switched on when there is a ring signal detected on pin RI of serial port. Wake-Up On LAN: When your computer is in power-down status, you can see LAN Link/Active LED is flashing. This status indicates that the LAN chip has entered standby mode and waits for Wake- Up signal. You can use other computers to wake up yours by sending ID to it. ID: ID is the MAC address of your system LAN. Every LAN chip has a factory-set ID, which you can find it from network information in WINDOWS. ID s format is xxxxxxxxxxxx Example ID:
